Armed robbers on Tuesday hit an upscale diamond jeweller in central Paris, making off with valuables estimated to be worth up to three million euros (four million dollars), police said.

The two men armed with handguns held up the De Beers stand in the Printemps department store in the early evening heist. A source close to the police inquiry said they did not fire their weapons and no one was injured.

De Beers declined to comment on the attack.

The heist comes less than 24 hours after masked thieves staged a spectacular five-minute robbery on the tarmac at Brussels airport, stealing diamonds worth $50 million (37 million euros).
